ROBERT W. JOHNSON, OF NEV BRUNSWICK, NEW JERSEY.

BAN DAG E.

SPECIFICATION forming' part of Letters Patent No. 700,938, dated May 27, 1902.

Application filed March 1, 1902.

To @ZZ whom, t may concern,.-

Be it known that I, ROBERT W. JOHNSON, a citizen of the United States, residing at New Brunswick, in the county of Middlesex and State of New Jersey, have invented certain new and useful Improvements in Bandages, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to surgical bandages, and is particularly suitable as a catauienial bandage.

The objects of my invention are to produce an inexpensive bandage having in its interior a series of flattened coils or layers of cobwebby ruinpled cellulose tissue or paper and above said layers a thicker layer of absorbent cotton and under the layers of cellulose tissue or paper a thick layer of natural or nonabsorbent cotton, the whole retained connected together with gauze textile, as illustrated in the accompanying drawings, in Which- Figure 1 represents a perspective view of a portion of a bandage constructed in accordance with my invention, said portion being cut off a short distance from one end of the bandage, the component parts thereof being cut off in the form of steps to show a portion of the surface of each material. Fig. 2 is a transverse section of the same on a slightlylarger scale.

In said drawings the numeral 2 represents a series of superposed iiattened coils or layers of cobwebby rulnpled cellulose tissue or paper obtained from wood-pulp mixed with hot water and made to pass on a sieve and around cylinders in a very thin sheet, where it is partly dried and then scraped therefrom. The production of said runipled cellulose-paper and its nature are fully described in United States Patent No. 468,480, dated February 9,

Serial No. 96,289. (No model.)

1892. Although said cellulose tissue-paper is very soft and flexible, sheets 0f it rubbed together do not become matted, as carded wood-pulp or cotton fibers are liable to be, and it has enough cohesion to retain its form even When subjected to friction, and this is of iinportancein catarnenial bandages. Upon this rumpled cellulose tissue or paper 2 is placed a layer of absorbent cotton 3 of a thickness equal to about three or more of said paper, and under it a layer of non-absorbent cotton 4: as obtainedA directly from the seed and slightly thicker than the layer of absorbent cotton, and the whole is inclosed in a strip of gauze textile, as cheese-cloth, of such width that its edges will overlap each other a sufficient distance to protect the component parts of the bandage against displacement when in use.

Having now fully described my invention, I claiml. An absorbent bandage consisting of series of layers of rurnpled cellulose tissue or paper, a thicker layer of absorbent cotton above said rumpled paper, another thick layer of non-absorbent cotton under said rurnpled paper, and a textile covering inclosing all the layers, substantially as described.

2. An absorbent bandage consisting of series of layers of rumpled tissue-paper, a layer of absorbent cotton above said paper, a layer of non-absorbent cotton under said rumpled paper, and a covering inclosing all the layers, substantially as described.

In testimony whereof I affix my signature in presence of two witnesses.

ROBERT W. JOHNSON.
